the interrupts are broken. they do not work as expected. something needs to be done, really.

#4 feat: log scopes a month ago

Ticket created by ~littleendian on ~littleendian/xcore-todo

There is a constant flow of messages in xcore logging everything. We need to include logging scopes to xcore's internal modules. It doesn't matter if the logging implementation is good or not, as at the end of the day after initial bootstrap the logs will be managed by the syslogd anyway.

#3 feat: safety checks with assert() a month ago

Comment by ~littleendian on ~littleendian/xcore-todo

Since commit 91e04e2c555736f4b35c797d371f4cd37ea4a4de there are a few things safety-checked:

x86.cpu.__readVendor:

Now checks if the provided buffer can contain 12 bytes or more.

x86.gdt.load:

Checks whether or not the last element in the provided table is a null entry.

x86.seg.reload:

Checks whether or not the actual segment selector is an executable one, if yes, fail.

NOTE: These safety-checks are ONLY AVAILABLE IN Debug and ReleaseSafe MODES. As a developer, if you build xcore in ReleaseFast or ReleaseSmall, your warranty is void, as the safety-checks will be omitted for performance reasons. If you develop like that, expect uncaught bugs.
